...HIGH SURF WARNING FOR SOUTH FACING SHORES OF ALL ISLANDS
TODAY...
...HIGH SURF WARNING FOR WEST FACING SHORES OF BIG ISLAND
TODAY...
...HIGH SURF ADVISORY FOR EAST FACING SHORES OF ALL
ISLANDS TODAY...

.Southwest swell from Hurricane Lowell produced surf along south
facing shores in excess of warning criteria overnight. This surf
continues into the early morning hours, which may continue to
bring damaging surf to portions of Kauai County with the
potential for significant damage to coastal properties and
infrastructure, particularly to those areas along the coast
exposed to the southerly swell over the next several hours. Surf
will quickly fall to advisory criteria and then below advisory
criteria by tonight.

A medium-period east swell from former Tropical Storm Karina combined
with east to southeast wind wave generated by Hurricane Lowell will
maintain advisory level surf along east facing shores this morning,
but will drop below advisory levels by tonight.

* WHAT...For south facing shores, surf 15 to 25 feet for Oahu, 12
to 20 feet for Maui County, and 12 to 16 feet for the Big Island
rapidly declining through the day, becoming 6 to 8 feet by this
afternoon. For west facing shores of the Big Island, surf
building to 12 to 16 feet rapidly declining through the day.

* WHERE...South facing shores of Kahoolawe, Lanai, Maui,
Molokai, Oahu and the Big Island. West facing shores of the
Big Island.

* WHEN...Until 6 PM HST this evening.

* IMPACTS...Very High...Expect ocean water surging and sweeping
across beaches, coastal benches, and lava flows creating the
potential for impacts to coastal properties and
infrastructure, including roadways. Powerful longshore and rip
currents will be present at most beaches. Large breaking waves
and strong currents may impact harbor entrances and channels
causing challenging boat handling.

Stay away from the shoreline along the affected coasts. Be
prepared for road closures. Postpone entering or leaving channels
affected by the high surf until the surf subsides.

SITUATION OVERVIEW
------------------

Hurricane Lowell has reached its closest point to the main Hawaiian
Islands around midnight and will begin moving away from the islands
this morning. However, this is not the time to let your guard down.
Damaging winds, heavy flooding rainfall, and extremely dangerous and
damaging surf will occur across the Hawaiian Islands at least through
the morning, and possibly through the day. A Hurricane Warning remains
in effect for Kauai and Niihau, and a Tropical Storm Warning for Oahu.

Current wind gusts appear to be in the 40 to 50 mph range on Kauai,
and 30 to 40 mph range on Oahu. It is important to note that winds can be
accelerated over and downwind of terrain, leading to areas of stronger
wind gusts. Winds will rapidly drop of by this afternoon.

Heavy downpours could lead to flash flooding on already saturated
grounds. Lingering rain bands will continue into Wednesday as Lowell
lifts away to the north and drags additonal tropical moisture in the
southerly flow. Additional rainfall for this event are 2 to 4 inches
on Kauai, 1 to 2 inches on Oahu and Maui County, and 3 to 6 inches on
Big Island with higher amounts occurring on south and eastern slopes.

A large south to southwest swell iwill continue this morning with
heights of 15 to 20 feet across south and west facing shores of Kauai
and 10 to 14 feet across the remaining south and west shorelines. Surf
is forecast to rapidly drop off by this afternoon.

POTENTIAL IMPACTS
-----------------

* WIND:
Potential impacts from the main wind event are now unfolding across
Kauai and Niihau. Remain well sheltered from dangerous
wind having possible significant impacts. If realized, these impacts
include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
routes impassable.
- Widespread power and communications outages.

Potential impacts from the main wind event are also now unfolding
across Oahu. Remain well sheltered from wind having limited to
extensive impacts.

Elsewhere across the Hawaiian islands, little to no impact is
anticipated.

* FLOODING RAIN:
Potential impacts from the flooding rain are unfolding across Kauai
and Niihau. Remain well guarded against life-threatening flood waters
having extensive impacts. If realized, these impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, arroyos, and
ditches may become dangerous rivers. In mountain areas,
destructive runoff may run quickly down valleys while
increasing susceptibility to rockslides and mudslides. Flood
control systems and barriers may become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.

Potential impacts from the flooding rain are unfolding across the
rest of the State of Hawaii. Remain well guarded against dangerous
flood waters having significant impacts.

* SURGE:
Little to no additional impacts are anticipated at this time
across the Hawaiian islands.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
Follow the advice of local officials

* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.

During the peak of the storm be ready to move quickly. Keep your
shoes on and rain gear handy. Boots and athletic shoes offer the
best foot protection if you become unexpectedly exposed to the
weather.

Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county or parish in which
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.

Keep your cell phone charged and in power-saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and
check-ins.

If you are prone to flooding be prepared for the possibility of a
quick and dramatic rise in water levels.

SITUATION OVERVIEW
------------------

Hurricane Lowell has reached its closest point to the main Hawaiian
Islands around midnight and will begin moving away from the islands
this morning. However, this is not the time to let your guard down.
Damaging winds, heavy flooding rainfall, and extremely dangerous and
damaging surf will occur across the Hawaiian Islands at least through
the morning, and possibly through the day. A Hurricane Warning remains
in effect for Kauai and Niihau, and a Tropical Storm Warning for Oahu.

Peak wind gusts across Kauai and Oahu over the past few hours were as
high as 80 mph. Current wind gusts appear to be slightly off the peak,
but still holding steady in the 60 to 70 mph range on Kauai, and 30 to
50 mph range on Oahu. It is important to note that winds can be
accelerated over and downwind of terrain, leading to areas of stronger
wind gusts. As winds turn southward, north facing slopes will be more
susceptable to downsloping effects.

Heavy downpours could lead to flash flooding on already saturated
grounds. Lingering rain bands will continue into Wednesday as Lowell
lifts away to the north and drags additonal tropical moisture in the
southerly flow. Additional rainfall for this event are 2 to 4 inches
on Kauai, 1 to 2 inches on Oahu and Maui County, and 3 to 6 inches
on Big Island with higher amounts occurring on south and eastern slopes.

An extremely large south to southwest swell is currently peaking with
heights of 20 to 30 feet across south and west facing shores of Kauai
and 15 to 20 feet same shorelines of Oahu. Surf is forecast to rapidly
diminish this morning, but will likely maintain the warning through
the morning for south and west facing shores. Storm surge of 1 to
4 feet on Kauai and Niihau will generate major wave run-up and coastal
inundation along exposed low lying areas of south and west- facing
shores.

POTENTIAL IMPACTS
-----------------

* WIND:
Potential impacts from the main wind event are now unfolding across
Kauai and Niihau. Remain well sheltered from life-threatening wind
impacts. If realized, these impacts include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
routes impassable.
- Widespread power and communications outages.

Potential impacts from the main wind event will develop across Oahu
this evening. Remain well sheltered from wind having limited to
extensive impacts.

* FLOODING RAIN:
Potential impacts from the flooding rain are unfolding across Kauai
and Niihau. Remain well guarded against life-threatening flood waters
having extensive impacts. If realized, these impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, arroyos, and
ditches may become dangerous rivers. In mountain areas,
destructive runoff may run quickly down valleys while
increasing susceptibility to rockslides and mudslides. Flood
control systems and barriers may become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.

Potential impacts from the flooding rain are unfolding across the
rest of the State of Hawaii. Remain well guarded against dangerous
flood waters having significant impacts.

* SURGE:
Potential impacts from the main surge and damaging surf event are now
unfolding across Kauai and Niihau. Remain well away from
life-threatening surge and extremely large surf having significant
impacts. If realized, these impacts include:
- Areas of inundation with storm surge flooding accentuated by
waves. Damage to several buildings, mainly near the coast.
- Sections of near-shore escape routes and secondary roads become
weakened or washed out, especially in usually vulnerable low
spots.
- Major beach erosion with heavy surf overtopping nearby roadways.
- Moderate damage to marinas, docks, and piers. Several small
craft broken away from moorings, especially in unprotected
anchorages.

Elsewhere across the Hawaiian islands, very large surf may produce
coastal inundation and some impacts to shoreline infrastructure.

* TORNADOES:
Potential impacts from tornadoes are unfolding across Kauai and
Niihau. Remain well braced against a dangerous tornado event having
possible significant impacts. If realized, these impacts include:
- The occurrence of scattered tornadoes can hinder the execution
of emergency plans during tropical events.
- Several places may experience tornado damage with a few spots
of considerable damage, power loss, and communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped or
uprooted, vehicles tumbled, and small boats tossed about.
Dangerous projectiles can add to the toll.

Prepare for a tornado event having possible limited impacts across
the rest of the State of Hawaii.

PRECAUTIONARY/PREPAREDNESS ACTIONS

SITUATION OVERVIEW
------------------

Hurricane Lowell has reached its closest point to the main Hawaiian
Islands. Expect damaging winds, heavy flooding rainfall, and extremely
dangerous and damaging surf to occur over portions of the Hawaiian
Islands and into Tuesday morning. A Hurricane Warning remains in effect
for Kauai and Niihau, and a Tropical Storm Warning is in effect for
Oahu. Storm preparations should be complete.

Damaging winds are now occurring on Kauai, Niihau and Oahu. Wind gust
reports since midday show highest values across Oahu and Kauai County
from 50 to 80 mph, with peak winds expected to last for a few more
hours tonight. It is important to note that winds can be accelerated
over and downwind of terrain, leading to areas of stronger wind gusts.
As winds shift to south overnight, areas affected by downslope wind
gusts will likely change.

Heavy downpours could lead to flash flooding and mudslides, especially in
steep terrain, and rainbands could become persistent and anchored in
some areas, exacerbating the flash flood threat. The risk of flash
flooding is greatest for Kauai and Niihau, where many stations have
measured 2 to 10 inches of rain with higher values in the upper
elevations. The flood threat also exists for all other islands due
to deep moisture surrounding Lowell. Over 20 inches of storm total
rain is possible over portions of Kauai, mainly over the interior
mountains, and up 12 inches remains possible over southeast Big Island.

An extremely large south to southwest swell generated by Lowell will
continue to rapidly build through the evening and peak tonight. A High
Surf Warning is in effect for south-facing shores of all islands and
for west-facing shores of the Big Island. Dangerously large and
damaging surf and coastal inundation are expected along the immediate
coast of exposed south and west-facing shores, particularly on Kauai
and Niihau and possibly Oahu. The highest surf may reach 20 to 30 feet
on Kauai and Niihau tonight, then rapidly diminish on Tuesday. Extra
large surf, on top of 1 to 4 feet of storm surge, will generate major
wave run-up and coastal inundation along exposed low lying areas of
south and west-facing shores, particularly for Kauai and Niihau and
possibly for Oahu.

Conditions will be conducive for fast-moving, short-lived waterspouts
and tornadoes in the rainbands associated with Lowell, mainly near
Kauai and Niihau. This threat will continue through tonight, then
diminish quickly Tuesday morning.

POTENTIAL IMPACTS
-----------------

* WIND:
Potential impacts from the main wind event are now unfolding across
Kauai and Niihau. Remain well sheltered from life-threatening wind
impacts. If realized, these impacts include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
routes impassable.
- Widespread power and communications outages.

Potential impacts from the main wind event will develop across Oahu
this evening. Remain well sheltered from wind having limited to
extensive impacts.

* FLOODING RAIN:
Potential impacts from the flooding rain are unfolding across Kauai
and Niihau. Remain well guarded against life-threatening flood waters
having extensive impacts. If realized, these impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, arroyos, and
ditches may become dangerous rivers. In mountain areas,
destructive runoff may run quickly down valleys while
increasing susceptibility to rockslides and mudslides. Flood
control systems and barriers may become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.

Potential impacts from the flooding rain are unfolding across the
rest of the State of Hawaii. Remain well guarded against dangerous
flood waters having significant impacts.

* SURGE:
Potential impacts from the main surge and damaging surf event are now
unfolding across Kauai and Niihau. Remain well away from
life-threatening surge and extremely large surf having significant
impacts. If realized, these impacts include:
- Areas of inundation with storm surge flooding accentuated by
waves. Damage to several buildings, mainly near the coast.
- Sections of near-shore escape routes and secondary roads become
weakened or washed out, especially in usually vulnerable low
spots.
- Major beach erosion with heavy surf overtopping nearby roadways.
- Moderate damage to marinas, docks, and piers. Several small
craft broken away from moorings, especially in unprotected
anchorages.

Elsewhere across the Hawaiian islands, very large surf may produce
coastal inundation and some impacts to shoreline infrastructure.

* TORNADOES:
Potential impacts from tornadoes are unfolding across Kauai and
Niihau. Remain well braced against a dangerous tornado event having
possible significant impacts. If realized, these impacts include:
- The occurrence of scattered tornadoes can hinder the execution
of emergency plans during tropical events.
- Several places may experience tornado damage with a few spots
of considerable damage, power loss, and communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped or
uprooted, vehicles tumbled, and small boats tossed about.
Dangerous projectiles can add to the toll.

Prepare for a tornado event having possible limited impacts across
the rest of the State of Hawaii.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
Follow the advice of local officials

* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.

During the peak of the storm be ready to move quickly. Keep your
shoes on and rain gear handy. Boots and athletic shoes offer the
best foot protection if you become unexpectedly exposed to the
weather.

Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county or parish in which
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.

Keep your cell phone charged and in power-saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and
check-ins.

If you are prone to flooding be prepared for the possibility of a
quick and dramatic rise in water levels.

If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
